Compressor HVAC: Description and Operation
Description
Through the development of electric compressors, fuel efficiency is improved and air conditioner can be implemented when the engine is stopped.
Operation Principle
Compression Part
One of the scrolls is fixed, while the other orbits electrically without self-rotating, to trap and pump refrigerant in the pockets between the scrolls.
Motor Part
Converts electric power into a mechanical motion with brushless DC motor.
Control Part
Converts direct current to 3-phase alternating current and alters the compressor speed to cope with cooling demand.
